0 , 2758 km = 27 , 58 ____________________

EX 3
1 ) 200 m + 19 km + 9 , 5 dam
= ____________________ , ____________________ km + 19 km + ____________________ , ____________________ km = ____________________ , ____________________ km

2 ) 1 , 5 hm + 12 , 5dam + 125 , 5 m
= ____________________ , ____________________ km + ____________________ , ____________________ km + ____________________ , ____________________ km = ____________________ , ____________________ km

3 ) 3 , 5 dam + 400 cm + 39 , 5 dam =
= ____________________ m + ____________________ m + ____________________ m = ____________________ m

EX 4 :
25 , 12 dm = ____________________ mm
9 , 8 km = ____________________ dam
89 , 7 dam = ____________________ , ____________________ km
7 , 3 cm = ____________________ , ____________________ dm

62 , 05 m = ____________________ , ____________________ dam

EX . 5 :
Les élèves de 6ème vont parcourir :
512 m + 59 dam + 6 hm + 5 , 6 hm
= 512 m + ____________________ m + ____________________ m + ____________________ m = ____________________ m

Les élèves de 3ème vont parcourir :
512 m + 59 dam + 5950 dm + 390 m + 1 , 2 km
= 512 m + ____________________ m + ____________________ m + 390 m + ____________________ m = ____________________ m
